ICHNEUMON-FLIES — GELINAE : MESOSTENINI 337 



Segments 2-4 of hind tarsus fuscous, brown at the ends ; nervellus broken near 

 its upper 0.37; first tergite in side view with distinct vertical wrinkles 

 between its spiracle and base 20. anagmus, new species 



3. Tergites 2 and 3 blackish, their apical margins ferruginous. 



10. fuscata, new species 

 Tergites 2 and 3 entirely ferruginous 4 



4. Hind coxa entirely fulvous; tegula and palpi white . . 4. coxalis, new species 

 Hind coxa black, if rarely ferruginous then the palpi fuscous; tegula and 



palpi variously colored 5 



5. Tergite 4 largely or entirely fuscous or black; notaulus reaching center of 



mesoscutum; segment 3 of maxillary jjalpus white. 



6. sulcata, new species 



Tergite 4 entirely ferruginous; segment 3 of maxillary palpus white, brown, or 



fuscous 6 



6. Temple at its upper 0.3 flat, concave, or faintly convex; occipital carina at 



its lower 0.3 very high, usually higher than 0.5 the width of third segment 

 of maxillary palpus (these two characters should be used together, with 



some allowance for variability) 7 



Temple at its upper 0.3 weakly to moderately convex; occipital carina at its 

 lower 0.3 not so high, usually less than 0.5 as high as the width of third 

 segment of maxillary palpus 11 



7. Tergite 8 fuscous; segment 2 of flagellum about 2.7 as long as wide. 



14. kathrynae, new species 



Tergite 8 ferruginous; segment 2 of flagellum about 3.0 to 4.5 as long as 



wide 8 



8. Temple at its upper 0.3 flat or weakly concave next to occipital carina; wings 



moderately infuscate; hind femur ferruginous to black 9 



Temple at its upper 0.3 faintly convex next to occipital carina; wings sub- 

 hyaline or weakly infuscate; hind feiuur black 10 



9. Vertical portion of epomia incomplete or very weak; temple at its upper 0.3 



flat or faintly convex; hind femur black . . 17. atrorubens, new species 



Vertical portion of epomia strong and complete, together with the dorsal part 



of epomia forming approximately a half circle; temple at its upper 0.3 more 



or less concave; hind femur ferruginous or black . 18. reflexa, new species 



10. Clypeus moderately convex; lower part of occipital carina a little higher than 



in subgracilis; sublateral portion of apical carina of propodeum oblique, 

 weakly curved; segments 2-4 of hind tarsus whitish to brown. 



13. exulans (Cresson) 

 Clypeus very strongly convex; lower part of occipital carina a little lower than 

 in exulans; sublateral portion of apical carina of propodeum almost hori- 

 zontal, more mesad curving strongly forward; segments 2-4 of hind tarsus 

 fuscous 15. subgracilis (Cresson) 



11. Apical 0.3 or more of first sternite bordered on each side by a longitudinal 



carina that projects ventrad (this carina represents the lower margin of the 

 tergite) ; punctures on head and body very dense. 



11. albitarsis (Cresson) 

 Apical 0.2 or less of first sternite bordered on each side by a ventrally project- 

 ing carina, or not at all bordered; punctures on head and thorax less 

 dense 12 



12. Clypeus moderately convex; apical margin of clypeus weakly arcuate or 



subtruncate 13 



Clypeus strongly convex; apical margin of clypeus rather strongly 

 arcuate 17
